Nursing calculators
Every calculator here shows the formula, your numbers substituted into it, and the working — because the answer is only useful once you can get it yourself.
IV infusion time
How long a volume takes at a set rate.
Formula: Total volume ÷ rate = infusion time in hours
Educational nursing-math tool. It works arithmetic on the values you enter and makes no recommendation about any patient. Verify medication calculations against your program, your facility's policy, the actual order, and any independent check your policy requires.
Where the boundary sits
CARE teaches nursing math. It does not recommend patient-specific medication doses. These tools work arithmetic on numbers you type — they have no drug list, no protocol and no patient model, so there is nothing here that could adjust a dose for renal function, run a sliding scale or titrate an infusion.
